FIG. 1 depicts a perspective view of an illustrative portable, magneticpositioning tool, according to one or more embodiments. The portablepositioning tool (“tool”) 100 can include a frame 105, a first supportmember 110, at least one extendable member (one is shown 115), and atleast one switchable magnet (one is shown 120). The first support member110 and the switchable magnet 120 can be disposed on or about the frame105. The first support member 110 can be disposed between a first end106 and a second end 107 of the frame 105 and the switchable magnet 120can be disposed on or about the second end 107 of the frame 105. Theextendable member 115 can be disposed on and extend from the firstsupport member 110 toward the switchable magnet 120.

In one or more embodiments, the frame 105 can be or include anelongated, rigid member, such as a rod, bar, beam, or the like. Theframe 105 can be solid, hollow, or a combination thereof. The frame 105can connect or otherwise position the first support member 110 relativeto the switchable magnet 120. The frame 105 can hold or otherwisemaintain a predetermined distance and/or orientation between the firstsupport member 110 and the switchable magnet 120.

In one or more embodiments, the extendable member 115 can include a body116 that can be disposed on or about a first side 111 of the firstsupport member 110 from which the extendable member 115 can extend. Thefirst side 111 of the first support member 110 can be oriented towardthe first end 106 of the frame 105 and the extendable member 115 canextend from the body 116, through the first support member 110, andtoward the switchable magnet 120 disposed on or about the second end 107of the frame 105. In one or more embodiments, the body 116 can beconnected or otherwise secured directly to the frame 105, therebyreplacing the first support member 110 with the body 116.

In one or more embodiments, the extendable member 115 can be adapted tomove in a linear direction. In one or more embodiments, the extendablemember 115 can be parallel to the longitudinal axis of the frame 105.The extendable member 115 can include a contact surface 117. When theextendable member 115 extends toward the switchable magnet 120, thecontact surface 117 can contact or otherwise engage with an object (notshown) disposed on a work surface (not shown) upon which the tool 100can be located. The contact surface 117 can be substantially parallel tothe contact side 127 of the magnet 120. A force exerted by theextendable member 115 can be sufficient to hold or otherwise reducemovement of the object, for example.

The extendable member 115 can include any system, device, or combinationof systems and/or devices suitable for linearly extending from the firstsupport member 110 toward the second end 107 of the frame 105. Asillustrated, the extendable member 115 can be a hydraulically actuatedram or piston. The body 116 can include a handle or lever 118 that whenactuated can linearly advance the extendable member 115. The body 116can include a valve 119 that when actuated can retract the extendablemember 115.

Other illustrative extendable members 115 can include, but are notlimited to, a pneumatically actuated ram or piston, a threaded roddisposed through a complimentary threaded hole disposed in the firstsupport member 110, and an electrically actuated ram or piston. Thethreaded rod can be linearly advanced and/or retracted through manualrotation or rotation using a motor, for example a battery powered motor.

In one or more embodiments, the first support member 110 can include acollar 113 disposed thereon, which can include a one or more holes 116disposed therethrough. One or more holes 108 can be disposed through theframe 105. When holes 108 and 116 are properly aligned, a fastener 114can be disposed therethrough to detachably attach or secure the firstsupport member 110 about the frame 105. The fastener 114 can be, but isnot limited to, a pin, bolt, screw, rod, or other device that can securethe first support member 110 at a desired position about the frame 105.Two or more holes 108 linearly spaced about the frame 105 can provide afirst support member 110 that can be linearly adjusted about the frame105 at two or more locations between the first end 106 and the secondend 107 of the frame 105.

In one or more embodiments, a first side or connecting side 133 of theswitchable magnet 120 can be connected to the second end 107 frame 105.The first side 133 can oppose a second side 127 of the switchable magnet120. As illustrated, a connection member or connection block 122 can bedisposed intermediate the first side 133 and the second end 107 of theframe 105. The switchable magnet 120 can be connected to the frame 105using any suitable fastening device, system, and/or method. Illustrativefasteners can include, but are not limited to, one or more bolts,screws, threaded rods, bolts and nuts, pins, rivets, and the like. Inone or more embodiments, the switchable magnet 120 via the first side133 can be connected to the frame 105 by welding.

In one or more embodiments, the switchable magnet 120 can be switchablebetween a magnetized state (“on”) and a non-magnetized state (“off”).The switchable magnet 120 can be switched between the “on” position andthe “off” position via a switch or lever 129. In one or moreembodiments, the switchable magnet 120 can be any magnet capable ofbeing switched between an “on” position and an “off” position. In one ormore embodiments, the switchable magnet 120 can be an electromagnet. Inone or more embodiments, the switchable magnet 120 can be or include oneor more permanent magnets. In one or more embodiments, the switchablemagnet 120 can include a housing 131 which can at least partially houseor enclose the switchable magnet disposed therein.

In one or more embodiments, the housing 131 can be or include one ormore materials having a low magnetic reluctance or a high magneticreluctance. The low magnetic reluctance materials can be ferrimagneticor ferromagnetic (“magnetically susceptible material”). The highmagnetic reluctance materials can include, for example aluminum,magnesium, and/or carbon fiber. In one or more embodiments, within thehousing 131, a first magnet or “lower magnet” can be held in a fixedposition beneath a second magnet or “upper magnet” that can be rotatedabout its axis. In one or more embodiments, the lower surface of thelower magnet can form part of the lower surface or “contact side” 127 ofthe switchable magnet 120. In one or more embodiments, the lower surfaceof the lower magnet can be recessed within the housing 131, such thatthe sides of the housing 131 provide a gap between a lower surface ofthe lower magnet and the contact surface 127 of the switchable magnet120.

The switch or lever 129 can rotate the second magnet relative to thefirst magnet within the housing 131. The second magnet can include anotch or groove adapted to engage or receive a bar (not shown) incommunication with the lever 129. The bar can be received inside agroove formed on a boss (not shown) that is connected to the lever 129.The lever 129 can have two or more positions, at least one of which isan “on” position and at least one of which is an “off” position.

In one or more embodiments, rotating the second magnet 180° about itsaxis can align the poles of both the first magnet and the second magnetin the “on” position to produce an external magnetic field. When soaligned, the north (positive) and south (negative) poles of the secondmagnet can substantially overlie the north and south poles of the firstmagnet, creating a strong external magnetic field about the housing 131.In one or more embodiments, at least a portion of the strong externalmagnetic field can be directed toward the contact side 127 of the magnet120. The contact side 127 can provide a surface along the switchablemagnet 120 that can, when switched to the “on” position, magneticallyattach to a magnetically susceptible surface (not shown).

In one or more embodiments, the housing 131 can be or include one ormore pole pieces that can enhance the magnetic functionality of theswitchable magnet 120. The shape or wall thickness of the pole piecesforming the housing 131 can increase or decrease the external magneticfield strength. For example, to provide a higher external magneticfield, the pole pieces can be shaped in such a way that they reflect thevariation of the magnetic field strength around the perimeter of thepermanently magnetized first and second magnets.

In one or more embodiments, the switchable magnet 120 can include one,two, three, four, five, or more independent switchable magnets. In oneor more embodiments, a switchable magnet 120 that includes a pluralityof switchable magnets disposed within the housing 131 can be switchedbetween the “on” and “off” positions via a single lever 129. In one ormore embodiments, a switchable magnet 120 that includes a plurality ofswitchable magnets disposed within the housing 131 can include two ormore levers 129 that can switch one or more of the switchable magnetsbetween the “on” position and the “off” position.

In one or more embodiments, the housing 131 can provide a waterproofand/or dustproof housing to protect the one or more switchable magnetsdisposed therein. This can provide a switchable magnet 120 suitable foruse in harsh, dusty, and/or wet environments. Additional details of asuitable switchable magnet 120 is further discussed and described inU.S. Pat. Nos. 6,707,360 and 7,012,495 and U.S. Patent ApplicationPublication No.: 2004/0239460.

In one or more embodiments, the tool 100 can further include a secondsupport member 125 connected to or otherwise disposed on or about theswitchable magnet 120, the frame 105, or both. The second support member125 can extend laterally from the switchable magnet 120 and/or the frame105 to provide support for the tool 100. The second support member 125can extend from the switchable magnet 120 and/or the frame 105 in adirection opposite the first support member 110, which can providesupport that can counter balance or counter at least a portion of aforce exerted on the tool 100 when the extendable member 115 extends andengages an object disposed on a work surface and/or the work surface(not shown) upon which the tool 100 is located.

The second support member 125 can be or include any suitable supportstructure, such as a rod, beam, plate, bar, or the like. In one or moreembodiments, a first side 140 of the second support member 125 caninclude one or more gussets or reinforcement members 142 disposedthereon. The gussets 142 can stiffen and reinforce the second supportmember 125. The gussets 142 can reduce and/or prevent movement of thesecond support member 125 relative to the switchable magnet 120.

In one or more embodiments, the second support member 125 can include asecond side 144 that can oppose the first side 140. The second side 144can contact a work surface on which the tool 100 can be located. In oneor more embodiments, the second side 144 of the second support member125 can be planar with the contact side 127 of the switchable magnet120. In one or more embodiments, the second support member 125 caninclude one or more contact points that can be planar with the contactside 127 of the switchable magnet 120.

The second support member 125 can extend from the switchable magnet 120and/or the frame 105 any suitable distance. In at least one specificembodiment, the second support member 125 can extend from the frame 105a distance equal to or greater than the distance the longitudinal centeraxis of the extendable member 115 extends from the frame 105. As thedistance the second support member 125 extends from the switchablemagnet 120 and/or the frame 105 increases, the second support member 125can provide a greater counter balance to a force that can be exertedfrom the extendable member 115 to the tool 100 when the extendablemember 115 extends and engages an object and/or a work surface,

In operation, the tool 100 can be disposed on a magnetically susceptiblework surface (not shown), so that the contact side 127 of the switchablemagnet 120 can be disposed on or proximate to the work surface. Theswitchable magnet 120 can be switched from the “off” position to the“on” position via the lever 129, thereby securing the tool 100 to thework surface. An object (not shown) to be secured between and/or to thework surface and the contact surface 117 of the extendable member 115can be placed in position and the extendable member 115 can be linearlyadvanced toward the object by actuating the handle 118. The extendablemember 115 can be linearly advanced, such that the contact surface 117of the extendable member 115 contacts the object disposed on the worksurface. The extendable member 115 can apply sufficient force toward theobject to securely hold or press the object on the work surface. Theswitchable magnet 120 can remain in contact with the work surface whilethe extendable member exerts the force or weight toward the objectand/or the work surface. To retract the extendable member, the valve 119can be actuated. In one or more embodiments, the extendable member 115can exert a force or weight toward the object and/or the work surface ofabout 20 kg or more, about 50 kg or more, about 500 kg or more, about1,000 kg or more, about 1,500 kg or more, about 1,800 kg or more, about2,000 kg or more, about 2,500 kg or more, or about 2,700 kg or more.

As discussed above, the position of the first support member 110 can beadjustable about the length of the frame 105. Adjusting the position ofthe first support member 110 can vary the distance between the contactsurface 117 of the extendable member 115 and the contact side 127 of theswitchable magnet 120. Linearly advancing and/or retracting theextendable member 115 can also vary the distance between the contactsurface 117 of the extendable member 115 and the contact side 127 of theswitchable magnet 120. Adjusting the position of the first supportmember 110 and the extent to which the extendable member 115 can beextended or retracted, can provide a tool 100 capable of positioning,holding, retaining, or otherwise securing objects (not shown) of varioussizes between a work surface and the contact surface 117.

FIG. 2 depicts a side perspective view of another illustrative portable,magnetic positioning tool 200, according to one or more embodiments. Inone or more embodiments, the portable magnetic positioning tool (“tool”)200 can be similar to the tool 100 discussed and described above withreference to FIG. 1. The tool 200 can further include one or morecounterweights 205. The counterweight 205 can counterbalance at least aportion of the weight of the first support member 110, the extendablemember 115, and/or the body 116 of the extendable member 115. In one ormore embodiments, the counterweight 205 can be disposed on the opposingside of the frame 105 as the extendable member 115. As illustrated,counterweight 205 can be disposed on a portion of the first supportmember 110 that extends away from the frame 105 opposite the side theextendable member 115 is disposed. As such, the counterweight 205 canprovide a stable tool 200. For example, the tendency for the tool 200 tolean or fall over due to the weight of the extendable member 115, thebody 116 of the extendable member 115, and/or the first support member110 can be reduced or eliminated.

In one or more embodiments, the counterweight 205 can be any materialthat adds a sufficient weight to the tool 200. In one or moreembodiments, the counterweight can be metal, concrete, a liquid filledcontainer, and the like. In one or more embodiments, the counterweight205 can include a battery, which can power an electrically actuatedextendable member 115. In one or more embodiments, the counterweight 205can be configured to include a plurality of weighted members, which canbe removed to or from the counterweight 205, thereby varying the weightof the counterweight 205. In one or more embodiments, the second supportmember 125 can be of sufficient weight that the second support member125 can function as the counterweight 205, thereby eliminating the needfor the counterweight 205.
